Patented Feb. 16, 1932 V UNITED STATES PATE OFFICE" JOSEPH J.woacmonowsxr, or GUDAHY,- wrsoonsim Assronon To A. o. smrrn CORPORATION,or MILWAUKEE, WISCONSIN, a CORPORATION on NEW YORK RAILWAY GRADECROSSI'LNG; CONSTRUCTION Application filed March 28, 1931 Serial No.525,946.

This invention relates to sheet metal rail- Wa grade crossingconstruction.

ne of the objects of the invention is to provide a sheet metalrailwaycrossing for which the supporting ties need notloe uniformlyspaced part. V

Another object is to provide such a crossing whichmay be l'eadil adaptedfor em ployment with rails of di erent heights.

Referring now to the drawings wherein is illustrated a preferredembodiment of the invention,

Figure 1 is an end elevation of a portion of a railway crossingconstructed according to the present invention, parts. being shown insection for the purpose of clearness; r h Fig. 2 is a longitudinalsection thereof taken on a plane indicated by the line 22 in Fig. 1; h

Fig. 3 is a topiplan view of Fig.1, certain parts being" omitted, andothers shown in section for the purpose of clearness; and Fig. 4 is afragmentary perspective View of one of the carrier bars.

Referring now more particularly to the drawings, the reference characterindicates one of a pair of rails of a railroad track which are securedto cross ties 11 in any suitable manner. Secured to the cross ties 11 bymeans of spikes 12 and extending parallel to the rails 10 are carrierbars 13.

The carrier bars 13 Iaremade of sheet 1 metal in the form of channelshaving upper horizontal web portions 14 anddownwardly extendingsupporting side. walls 15. The side walls 15 have their lower edgeportions bent inwardly toward each other in aplane parallel to theupperweb 14 to. form flanges 16 which constitute means for providingsubstantial bearing surface for the carrier members and also to serve asmeans for securing the same in position. a h

In securing thecarrier bars 13 tofthe cross ties. 11, the spikes 12 arepassed through alignedholes 17 and 18in the webportion 14 and bearingflanges 16, respectively and driven into the cross ties 11. This mannerof securing the carrier bars to the ties prem vents spreading of theside Walls thereof dur upper web thereof predetermined intermeans ansecuringthe same in position on ing passage of heavy loads over thecross- Thecarrier bars areprovided with pairs of ears 20 which arestruckup from the j u vals to providefimeans for securing tie bars.

21thereto.j The tie bars 21 are also made of sheet metalin the form ofchannels and have upper horizontal web portions 22 and downwardlyextending side walls 23. The side walls 23 have their lower edgeportions bent inwardly toward each other in a plane paralleltothe uppenweb 22 to formflanges 2 1 whi'chprovide substantial bearing surfacesforthe tie bars andalso serve as the carrier bars.

. inturned flangesQt of the bars are adapted to underlie the pairs ofstruck up cars 20 of the carrier bars to maintain the tie barsinadjusted jposition. The bearing flanges 2 1 01 the tie bars 21 havenotches 25cut1inthem at intervals corresponding to the spacing of thecarrier bars13,thus per mitting the tie barsjto he slipped over thestruck up ears 20 and moved endwise over the Webs 14 into theirifinallyadjusted positions. lVhen the tie bars are. thus positioned, the"flanges 2 1". interlock. with the struck up ears 20 to prevent verticalor lateral movementof the tie bar relative to the carrier'bar, v i

The tie bars 21 are provided with a plurality of pair sfofears 26 which'are struck up from thesupper web thereof to provide means for securingcrossing elements 27 thereto in parallel juxtaposed relation. Thecrossing elements 27 have inturned bearing flanges 28 which are adaptedto underlie the struck up ears 26 ofthe tie bar to secure the crossingelements in adjustedjposition. The bearing flanges 28 of the crossingelements have notches 29 at spaced intervals correspending tothefldistance between the pairs of struck up ears 20 on carrier bars 13.y

; In'the installation of a crossing, the carrier bars13 are firstsecured by spikes 12 to the cross ties 11 with corresponding pairs ofstruckup ears 20 of the several carrier bars in cross alignment; The tiebars are then tohold the tie bars in position. The several tie ;bars areso adjusted in position that corresponding pairs of struck up ears 26 ofthe several tie bars are in crossalignmentr Crossing elements 27 arethen secured to the tie bars in a manner similar to-the securing of thetie bars to the carrier bars. 7 v

' By providing the carrier bars 13, a tie bar 21 need not be positioneddirectly above a cross tie 11 as is thecase when no carrier bars areused, thereby expediting the installation of'a crossing at. a placewhere the cross ties are non-uniformly spaced or are spaced in such amanner as to make it impossible to locate the tie bars in the properposition.

' Furthermore, by providing carrier bars of different heights it ispossible to adapt the crossing to use with rails of correspondinglydifferent, height-s without necessitating a change in the height of thetiebars or crossing elements.

Although the foregoing description is necessarily of a detailedcharacter in order to completely set forth the invention,it is to beunderstood that the specific terminology is not intended to berestrictive or confining and it is to be further understood that variousrearrangements of parts and modifications of structural detail may beresorted to without departing from'the scope or spirit of the inventionas herein claimed.

' .Having thus described the invention, what isclairned anddesired to besecured by Letters Patent is:

v 1. In a sheet metal railway grade crossing, the combination with therails and ties of sheet metal carrier bars extending substantiallyparallel to the rails and fastened to the ties, sheet metal tie barsextending transversely to said carrier bars and supported thereby, meansintegral with said carrier bars and tie bars for interlocking the sameand preventing relative vertical movement,

and crossing elements supported upon said tie bars and fastened theretoin parallel juxtaposed relation to provide a tread surface substantiallyflush with the. tops of the rails.

2. In a sheet metal railway grade crossing,
